I really hate you.
You are always around and hard to get away from.
"I like you"? Just shut up already.
It troubles me when something is expected from me.
It'll be over as soon as I show my lovestruck inner self.
It's boring if I show it now, right? So not yet!

Basically speaking,
love is weird even when you look at it.
It's a very stupid sickness.
Indeed, those buoyant lovestruck kids,
who look like there's something wrong with their head,
should be sent to the hospital right away.

Truthfully, I know, too,
that love is not that bad.
I know, but still,
it'll be bad if I let it get out of control.
It'll be over as soon as I show my lovestruck inner self.
It's boring if I show it now, right? So not yet!

I really hate you.
You are always around and hard to get away from.
"I like you"? Just shut up already.
It troubles me when something is expected from me.
It'll be over as soon as I show my lovestruck inner self.
It's boring if I show it now, right? So not yet!

Lyrics from Animelyrics.com

In regards to the title, if you classify someone as TSUNDERE, that basically means that they are normally aggressive or come off as harsh, but they suddenly fall in love.
It can also just mean that they appear harsh on the surface, but underneath, they are lovestruck. It's combines the terms tsuntsun (meaning aloof or pointed) and deredere (lovestruck or fawning).

* Translation of the SECRET CODE:
"I really like you.
I'm very happy when I'm with you.
I really like you."
